` Be itlrn'own that We, JOHN WRIGHT SEA- VER., a 'citizen-of the United States, and a residentof Cleveland, Ohio, and ALEXANDER 5 LESLIE, a subject lof' the' King of Great- 1 5 the-screening of the same, when such screening is desired, and the loading of the mate rial into either open or box cars. 'l'lus obn lect we attain 1n the manner hereinal'ter set forth, reference being had tothe acconipany- 20 inedrawmgs, in which@ illigure l is a side elevation of one form of apparatus embodyingonr invention. Fig. 2,

is a similar view of `another forni of'said apparatus', and Figs. 3 and 4 are respectively 2 5 an end elevation and a plan ofthe apparatus shown in Fig. 2, these views being to so'ine.

. extent diagrammatic in order to more clearly bring out the features whicli it is desired to illustrate.

Referring, in tl'ie first instance, to Fig.. l, A represents -a cantalivcr-erane of the travel'- ing gauntree type, the vertical legs for posts of'tliis crane being mounted'upon rails laid parallel with the pier side or doclehead, The

4 35'..trussed horizontal member X of' this crane has atraveliiter trolley, 'from which'is suspended a grabelnu-.lnzt yW or other receptacle `for receiving the mantente of the vessel Z orother carrier whose cargo is to be unloaded, 4o said bucket being capable of being raised and lowered so that it can descend into the hold of the vessel, receive its lood, elevate the same., and traverse it to any part of the structure X,

Suit-ably supported in an elevated position upon the crane A is a hopper B, which has three outlets C, D, and E, the outlet l) being a vertical outlet loading from the bottom of the hopper, the outlet E boing an inclined 5o spout extei'iding from one -side ot the hopper,

and the outlet ll being an elbow-spout extending from the other side oi the hopper, each nick, and

of these outlets being provided With-a. suit` able regulatinggate' or valve F.

Between the rails which suplirt the crane t A is a track (lV for railway-cars which may be of varying types-such as hopper, gon- (lola, or box cars-the elbowpipe C rovi`d, ing forthe flow of material from. the io per B into and through a side door of such oxcar and the delivery end of suchelbow-pipe C having an extensioibchute C for directing the material into the distributing spoutor chute' T of a car-loader U, which is mounted to travel alongside of or parallel with the. crane, so that material from the hopper B can be discharged into any desired portion of the interior ,of the box-car H, the sliding chute C of the elbow-pipe C being retracted when it is desiredto rnove either car or crane. relatively to each other. i

in loading hopper or gondola cars, which are open at the top, lthe outlet D is employed, as the granular material can in this case. ilo W directly downward from the hopper into: the car.

When it is desired to screen the material after it is unloaded and before being reloaded,

We employin connection with the crane A and its hopper B,- Ineans for carrying the, material to said screens and for directing the various-grades of material Which-result from the screeningi operation to different receptor cles or points of discharge. v

ln the construction shown in Fig. 1 J represents a traveling gauntree-crane mounted upon rails parallel Witli those which carry the crane A, this crane J having mounted upon it an inclined clevatingconveyer.K, Which can receive material from the spout E of the hopper B, v said velevator being movably mounted upon inclined rails L of the crane J, so that 1t can be lowered to receive material i from. the spout or raised so that its lower ond will not project between the upright posts of the crane A, and hence Will not interfere with longitudinal movement of either crane relative to the other.

Beneath' tl ie upper portion of the elevatingn convever K are a pair of inclined screens LGO M M. located4 one above the other, the head' ol the uppermost screen receiving the material delivered from the head of the conveyor K, so that seid material will iow by gravity of material below through said upperscreen and falling onto the lower screen' M', which eiects a still fuir-l asses througli the screen M being deposite upon a horizontal conveyor S, which delivers the same atene side of the crane J. i The material discharged from the uppermost screen M falls inte a hopper l,4 having an inclinedl .spout l, with sliding end chute I2, sothat said material can Vbe delivered .into a boxcar or-into the chute T 'of the loading device U The materialwhieh is delivered by the lower screen M falls upon a ,directing chute or platform M2 and is thereby directed into a car V, ruiming down said uppermost screen' M, all portions a certain ther separation, lhe fnaterial which for distribution Within said car.

The structure comprising the inclined rails L and the casing which carries thescreens M M is pivot-ed at P to a projecting portion 'of the crane structure J, and the up 'er ends Jjilstaiile screw connections-Q, extendingto some fixed portion of the crane J, sothat theycan be adjusted in order tovary the Aangle ofl the as may 'be deof the-rails L are provided with a ciinveyer K and screens lvl M, sii-ed.

Having thus described our invention, we claim and desire to secure by Letters flatentsize passing 'gliaveringthe same to the head of the screen T he capacity oi" the bin 'B and hopper l should. be such that material can be vdeliv-v ered. to and stored in'either of said recep-. tardes, while outilow from Athe saine is cut oli- 1.
